The energy of a photon that would move an electron from level 2 to level 5 : B. 4.8 eV

<h3>Further explanation</h3>

The electron energy at the nth shell can be formulated:

<h3>En = -Rh / n² </h3>

Rh = constant 2.179.10⁻¹⁸ J

So the electron transfer energy (ΔE)

ΔE = E final- E initial

energy at n=2(level 2) = -5.3 eV

energy at n=5(level 5) = -0.5 eV

So the energy absorbed :

\tt \Delta E=-0.5-(-5.3)=-0.5+5.3=4.8`eV
